Hi, Please am currently searching for any idea on the cost of pickling stainless steels vessels/tanks. please does any one have any idea how this is carried out?

NB:The vessels in questions have a dia range from 0.2 to 1.6m with the cylindrical lengths in the range of 0.7 to 9.6m.

Thanks

Hi. If by pickling you mean passivate, this is done typically using nitric acid, or the more eco-friendly citric acid. Temperatures are slightly elevated; and both yield excellent results. Of course extensive post-rinsing is required, including de-ionized water, to ensure surface purity. Consult ASTM for specifications. If you're located in the Midwest, a company called Luke Engineering & Mfg. Co. (Wadsworth, OH) will take good care of you. Tel: (330) 335-1501 Best wishes.
